PE42742中文资料UltraCMOS® SPDT CATV Switch数据手册pSemi规格书

描述 Description

The PE42742 is an SPDT UltraCMOS® switch designed for broadband applications such as CATV, DTV, multi-tuner DVR, set-top box, PCTV and game boxes. It meets FCC 15.115 spec of 80 dB isolation @ 216 MHz and offers high isolation and low insertion loss in both a powered and a unique unpowered default state. The PE42742 covers a broad frequency range from 5 MHz to beyond 2200 MHz with a single positive supply and CMOS control. It provides a smaller, cost effective, more reliable and manufacturable alternative to mechanical relays in set-top box applications.
